Auditorio Banamex (former Auditorio Coca-Cola or Auditorio Fundidora) is an indoor amphitheatre, located in Fundidora Park, in Monterrey, Nuevo León. It was the primary venue for concerts until the Arena Monterrey opened in 2003. The amphitheatre opened in 1994 with a sponsorship by The Coca-Cola Company. When the venue was used less frequently, Mexican financial group Grupo Financiero Banamex, became its new sponsor with a $20 million investment. The venue closed for nearly two years to set forth renovations, which included updating the overall structure of the venue, converting it to an indoor amphitheatre.
